50+ Filters Explained: How to Set Up the Perfect Product Finder Search
Not all filters are equal. Some eliminate bad products, others surface hidden gems. Here is exactly what each filter group does and how to combine them for maximum precision.

Product Finder gives you access to over 50 individual filter criteria. Used randomly, they produce mediocre results. Used with intent — understanding what each filter actually controls and why — they become a precision instrument for finding exactly the type of product opportunity you are looking for.
This guide breaks down every filter group in the Product Finder panel, explains the logic behind each one, and shows you how to combine them into a filter stack that consistently surfaces high-quality opportunities.

Group 1 — Sales & Rank
This is the most fundamental filter group. BSR and monthly unit sales together define the velocity tier you are targeting — how popular the product needs to be, and how consistently it sells.
- Best Sellers Rank (BSR) min/max — sets the BSR window. A max of 15,000 in most categories means the product has genuine, consistent sales. Setting a minimum (e.g. 1,000) excludes dominant category leaders that are impossible to displace. The sweet spot for new entrants is typically BSR 3,000–15,000
- Monthly Sales (Units) min/max — direct unit sales filter. Use a minimum of 200–300 units/month to confirm the product has real recurring demand beyond occasional purchases. Setting a maximum prevents you from entering hyper-competitive volume niches where established sellers have unassailable advantages
BSR and monthly sales are correlated but not identical. A product with BSR 5,000 in a large category like Kitchen & Dining might sell 800 units/month. The same BSR in a small sub-category might mean 50 units/month. Always use both filters together rather than relying on BSR alone.
Group 2 — Reviews & Rating
Review count is the single most important barrier to entry on Amazon. This filter group lets you control both the competitive difficulty of the niche and the quality signal the product sends to buyers.
- Review Count min/max — the max review count is your barrier control. Under 100 reviews: very easy entry, fast path to parity. 100–500: moderate barrier, achievable with solid launch strategy. 500–2,000: high barrier, requires clear differentiation. Setting a minimum review count (e.g. 20) filters out brand-new products with no track record
- Minimum Star Rating — filters out low-quality niches. A minimum of 3.8 stars removes products with fundamental buyer dissatisfaction while preserving products with improvement opportunities. Avoid niches where the top products average below 3.5 — buyer dissatisfaction at that level usually indicates a product category with intrinsic problems
Group 3 — 90-Day Averages
This is the most underused filter group and arguably the most powerful. Point-in-time metrics — current BSR, current price, current sales — can be deceiving. A product might be having its best week ever right now, or its worst. The 90-day averages smooth out these fluctuations and give you a more reliable picture of sustained performance.
- 90-Day Average BSR — more reliable than current BSR for filtering. A product whose current BSR is 5,000 but whose 90-day average is 15,000 is having a temporary good period — not a reliable baseline. Set the 90-day average max to match or slightly exceed your current BSR max to filter for products with consistent performance
- 90-Day Average Price — the price a product actually sells for over time, not just today. Use this instead of current price to avoid filtering in products that are temporarily discounted or temporarily premium-priced
- 90-Day Average Sales — sustained monthly sales volume. More reliable than point-in-time estimates for confirming real demand exists at the velocity you need
The 90-day average filters are powered by Keepa API data pulled through AMZDataLens. They reflect actual observed performance over 90 days, not estimates. When you set a 90-day average BSR max of 20,000, you are filtering for products that have maintained that performance level consistently — not just happened to hit it today.
Group 4 — Trend & Competition
Trend and competition filters let you select for market dynamics, not just current performance. A product with good current metrics but worsening trends is a declining opportunity. A product with moderate current metrics but improving trends is an emerging one.
- BSR Trend Direction — filter for products whose rank is improving (demand growing), stable, or declining. For new entrants, 'improving' is the strongest signal: you are entering a niche that is growing, which means rising tide lifts all boats
- Competition Level — AMZDataLens classifies competition as Low, Medium, or High based on the number of active sellers, their review counts, and BSR distribution. Low and Medium are the target zones for new entrants
- Active Seller Count — set a maximum active seller count to avoid ASINs where too many sellers are already competing. More than 5–6 active sellers on a single ASIN typically means Buy Box rotation and price pressure
Group 5 — Buy Box & Listing Flags
These filters control market structure — who is selling, how, and under what conditions. They are essential for avoiding structural traps that look attractive on the surface but are actually very difficult to enter profitably.
- Fulfillment Type (FBA/FBM) — filter for FBA only to ensure you are comparing apples to apples on logistics costs and Buy Box eligibility. FBM sellers have different cost structures and Buy Box dynamics
- Amazon Listed — exclude ASINs where Amazon itself sells as a 1P vendor. Amazon almost always wins the Buy Box on ASINs where it sells directly, making third-party entry very difficult
- Buy Box Price — set a minimum and maximum Buy Box price to target your desired price tier. The $15–$60 range is the sweet spot for FBA economics — high enough for meaningful margins, low enough for impulse purchasing
- Subscribe & Save — filter for products eligible for Subscribe & Save if you want recurring revenue potential, or exclude them if you want to avoid competing with subscription-locked buyer bases
Always filter out Amazon 1P listings for new product research. Amazon's presence on an ASIN is not a signal of opportunity — it is a signal of competition you cannot win. Use the Amazon Listed filter set to 'No' or 'Unknown' to exclude these ASINs from your results.
Group 6 — Title Keywords
Title Keywords is one of the most powerful and least obvious filters in Product Finder. It searches for products whose Amazon listing title contains a specific phrase — without running a keyword search. This is fundamentally different from Product Research keyword search.
In the shaker bottle example: setting Title Keywords to 'Shaker bottles' finds every product across Amazon whose listing title contains that phrase — regardless of category, regardless of how you would normally search for it. This surfaces variants, adjacent products, and cross-category opportunities that pure keyword search would miss.
- Use broad terms to cast a wide net — 'shaker' instead of 'protein shaker bottle' finds a much wider product universe
- Use specific terms to find precise sub-niches — 'pancake batter dispenser' instead of 'kitchen tools' finds exactly the sub-niche you are researching
- Combine with category filters to find keyword-specific products within a target category — Title Keywords 'dispenser' + Category 'Kitchen & Dining' finds every dispenser-type product in that category
- Leave it blank to discover products you would never have thought to search for — the most powerful mode for genuine niche discovery
Group 7 — Weight & Dimensions
FBA fees scale with product size and weight. Filtering by physical characteristics is not just about logistics — it is a profitability filter. Products that are heavy, oversized, or irregularly shaped have dramatically higher FBA fees that can destroy margins even on well-selling products.
- Item Weight max — keep this under 2kg (4.4lbs) for standard FBA rates. Above this threshold, you move into higher fee tiers that significantly reduce net margin
- Package Dimensions — filter for products that fit within standard FBA size tiers. Oversized products incur additional monthly storage fees and higher fulfilment fees
- Use weight filtering as a proxy for margin protection — a lightweight product at $25 with $5 FBA fees leaves far more margin than a heavy product at $25 with $12 FBA fees
Group 8 — Categories
Category filtering narrows your search to specific Amazon browse nodes. This is most useful when you have already identified a category you want to explore and want to find the best opportunities within it, rather than discovering products across all categories.
Do not use category filtering too early in your research process. The most valuable Product Finder discoveries often come from products appearing in unexpected categories. Run a broad, uncategorised search first to see what surfaces — then use category filters to drill into promising areas.
Group 9 — Brand & Seller
Brand and seller filters are most useful for competitive intelligence rather than initial discovery. Use them to find all products from a specific brand or seller you are researching, or to exclude well-known brands from results when you want to focus on opportunities where you are not competing against established brand equity.
Group 10 — Date & Tracking
Date filters let you find products by how recently they were listed on Amazon. This is one of the most underappreciated filters for trend identification.
- Listed After — find products launched in the last 6–12 months that are already performing well. A product listed 6 months ago with BSR under 10,000 and under 100 reviews is a fast-growing opportunity with a low review barrier
- Listed Before — find established products with long track records. Useful when you want to validate that demand has existed for years, not just months
- In Saved Items — filter to see only products you have already saved, useful for reviewing your candidate shortlist
Putting it all together — the precision filter stack
The most effective Product Finder searches combine filters from multiple groups into a coherent stack. Here is a proven combination for finding fast-growing, low-competition opportunities:
- BSR: 1,000–15,000 | Monthly Sales: Min 300 | 90-Day BSR Average: Max 20,000
- Review Count: Max 300 | Min Rating: 3.8 stars
- BSR Trend: Improving | Competition: Low or Medium
- Fulfillment: FBA only | Amazon Listed: No
- Item Weight: Max 2kg | Buy Box Price: $15–$60
- Listed After: 12 months ago (to find growing products, not just established ones)
Save your best filter combinations using the browser bookmark or note them down. Product Finder searches are not saved between sessions by default. Your most productive filter stacks are valuable IP — they represent the exact criteria that define your target opportunity profile, refined through research experience.
Filters are not constraints — they are a language for describing the opportunity you are looking for. The more precisely you can articulate what a good product looks like in data terms, the more precisely Product Finder can surface it. Building your filter intuition takes time, but every search that returns surprising results teaches you something about how the market is structured.
